What is the estimated regression equation? [2 points] What proportion of the sample variability in production time is explained by the two independent variables? [2 points] Suppose a circuit board had two additional manually-installed components. What is the estimated change in production time by adding these two components? [3 points] Comment on the individual significance of the two independent variables. Assume an alpha-level of 0.05 in your analysis. [4 points] Use this estimated regression model to predict production time for a circuit board with 475 machine-installed components and 16 manually-installed components. [2 points]
